But I don't think I am using hplip. I am using cups. perhaps that is the problem. But I doubt it. I am pretty sure that the new slackware kernel just doesn't support usb printer input on some of the not-so-old hp laserjets.

That's the "good" version of hplip. The kernel only sees it as usb, and cups/hplip pickup the tab from there. Its up to cups/hplip to do anything printer-specific at that point. Try doing the hplip configuration for cups

I think that's my problem. The kernel doesn't see anything when I plug my HP laserjet 4Mplus into the usb port. Nor does it see my HP laserjet 6MP. Tried different cables. If it would see it, I could configure it. As it is, I have to use the parallel port, which is kind of slow.

What I meant, is the kernel is supposed to only care if it USB in the case of printers. The rest is done by cups and hplip.

lsusb should list all devices that the kernel sees as USB. See if your printer is listed there. This will confirm that the USB port on your printer is functioning correctly.

And as nightflier mentions, there's a command like hp-makeuri that you'll need to run to give the correct info to cups. This is one area that we really need updated documentation on, I can't remember the specifics of what needs to be done here to get hplip and cups to run together. Maybe some generic hplip/cups documentation has the needed info?

I still think there is a problem with Cups 1.4.6 or VL 7 rc2. It won't see my Xerox copier which I want to use to print wireless. Perhaps this is fixed in the latest RC. Hope so. I can get on the copier, typing its url, so I know something is working.

"Add Printer" doesn't see it the Xerox even though I am on the Xerox' URL. I have to go to Internet Printing Protocol (Http) and put it in there. Then I can print with it and Cups sees it in "manage printers."
